Which bit of the process is it that you're stuck on?  I'm guessing that 
you may have used mkgmap to create one or more .IMG files and are 
looking for a way to wrap them together into a "gmapsupp.img" and send 
it to the device?  If so, then I probably can't help as I've always 
cheated and used the free (as in beer but not speech) "sendmap20" on MS 
Windows from cGPSmapper to bundle .img files together and send them.

Also, what Garmin model are you interested in loading the resulting map 
on?  Of the handheld GPSs, some have memory cards, some don't, and some 
are USB accessible and some aren't.  If you've got one with a memory 
card in it and turn the USB interface on on the device you should be 
able to access the "Garmin" directory as a bit of mass storage as per:

At the risk of stating the bleeding obvious there are also various 
suggestions here:

and it, and its talk page, get updated pretty regularly for new Mkgmap 
features etc.
